It’s fun to uncover something that you aren’t supposed to know about—
many software applications and movies on DVD contain what are known
as “easter eggs.” However, imagine finding something that you aren’t supposed
to find that turns out to be useful and informative.
In this chapter, we are going to hunt for GPS easter eggs, delving into the
secrets that lie behind the standard menus on your GPS unit to find useful
features and diagnostic screens that can give you information about your
system and troubleshoot problems that you might have.

In the “old days” of the Internet, most web pages were nothing more than text files
containing HTML. When people visited your site, your web server simply made the
file available to their browsers. This approach started out fine, but as web sites grew,
and issues such as design and navigation became more important, developers found
that maintaining consistency across hundreds of HTML files was becoming a massive
headache.

Apart from writing books like this one, I write code. I make my living by building
web sites and applications as, I’m sure, many readers of this book do. I use CSS to
complete jobs every day, and I know what it’s like to struggle to make CSS work
when the project needs to be finished the next morning.
When I talk to designers and developers who avoid using CSS, or use CSS only for
simple text styling, I hear over and over again that they just lack the time to learn
this whole new way of working. After all, tables and spacer GIFs function, they...

"This book covers not just the glamorous aspects such as the intrusion act itself, but all of the pitfalls,contracts, clauses, and other gotchas that can occur. The authors have taken their years of trial and error, as well as experience, and documented a previously unknown black art."
-From the Foreword by Simple Nomad, Senior Security Analyst, BindView RAZOR Team Penetration testing--in which professional, "white hat" hackers attempt to break through an organization’s security defenses--has become a key defense weapon in today’s information systems security arsenal.

SQL injection is a technique often used to attack data driven applications [1]. This is done by including portions of SQL statements in an entry field in an attempt to get the website to pass a newly formed rogue SQL command to the database (e.g., dump the database contents to the attacker). SQL injection is a code injection technique that exploits a security vulnerability in an application's software. The vulnerability happens

In this age of universal electronic connectivity, of viruses and hackers, of
electronic eavesdropping and electronic fraud, there is indeed no time at
which security does not matter. Two trends have come together to make the
topic of this book of vital interest. First, the explosive growth in computer
systems and their interconnections via networks has increased the depen-
dence of both organizations and individuals on the information stored and
communicated using these systems.

In cryptanalysis and computer security, password cracking is the process of recovering passwords from data that has been stored in or transmitted by a computer system. A common approach is to repeatedly try guesses for the password. Another common approach is to say that you have "forgotten" the password and then change it.

In computer security and programming, a buffer overflow, or buffer overrun, is an anomaly where a program, while writing data to a buffer, overruns the buffer's boundary and overwrites adjacent memory. This is a special case of violation of memory safety.

you’re an app developer with a solid foundation in Objective-C, this book is an absolute must—chances are very high that your company’s iOS applications are vulnerable to attack. That’s because malicious attackers now use an arsenal of tools to reverse-engineer, trace, and manipulate applications in ways that most programmers aren’t aware of.

Viruses, worms, Trojans, and bots are all part of a class of software called malware. Malware or malicious code (malcode) is short for malicious software. It is code or software that is specifically designed to damage, disrupt, steal, or in general inflict some other “bad” or illegitimate action on data, hosts, or networks.

An exploit (from the verb to exploit, in the meaning of using something to one’s own advantage) is a piece of software, a chunk of data, or sequence of commands that takes advantage of a bug, glitch or vulnerability in order to cause unintended or unanticipated behaviour to occur on computer software, hardware, or something electronic (usually computerised). Such behavior frequently includes such things as gaining control of a computer system or allowing privilege escalation or a denial-of-service attack...
